Dc are 2.8 and 1, and share at the moment but are different sex so I'm guessing will need separate rooms in a few years. We also need a guest room as have my mum and mil live abroad and when they visit, they stay for at least a month each. Our current flat (rental) is 1300+ sqft. We are looking to buy but if we wanted a nice location will have to compromise on size (probably down to 1100sqft). Should we aim to move further out and get a bigger space? Will we need more as the kids get older??
